As mentioned, this happens after a 'make build' or a 'make includes' and
always somewhere in usr.bin. It does not happen when I manually cd to
each dir and do a 'make includes' there.

A 230MB MO is mounted on /usr/src, /var/obj is union-mounted on top;
arch is mac68k.
Does this ring a bell for anyone? Should I send-pr?
